To all 'whom t may concern: p

Be it known that I, EDWARD C. BoRoI-rnns, a citizen of the United States of America, and a resident oit Chicago, county of Cook, and State of lllinois, have invented certain new and useful Improvements in Articles ol" Manufacture and Methods of Making Same, of which the following is a specilication.

This invention relates to articles of manu-- facture of an ornamental nature, and to methods of forming same, and particularly to methods of attaching plates of celluloid or the like to plates of metal.

The main objects of this invention are to provide an improved structure for kornamental articles of manufacture, such as belt buckles; to provide improved means and methods for attaching plates of unlike character to each other, and especially, means for attaching plates of readily cemented composite character to backing plates of metal. A further object is to provide a process whereby a celluloid plate may be secured to a metal plate by rigid metal fastening means in such manner as to present an unbroken integral appearance. A. still further object is to provide a method for ornamenting the Jface of the celluloid plate by attaching a decorative design thereto in a substantially integral manner.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which- Figure 1 is a plan of a belt buckle embodying this invention, certain details immaterial to this invention being omitted.

Fig. 2 is a side elevation of said buckle.

Fig. 3 is a section on the line 3 8 of Fig. 2. y

Fig. 4 is a section on the line 4-4 of Fig. 2.

Fig. 5 is an enlarged section on the line 5*5 of Fig. 1, showing the device in a partly finished state.

Fig. 6 is a fragmentary view of a section similar to Fig. 5, but showing the result of an additional step inthe process of manufacture.

Fig. 7 is a section on the line 5-5 of Fig. 1, as the device appears when finished.

Referring to the structure shown in the drawings, the metal plate 1 has secured thereto a celluloid plate 2 which in turn has secured to its iront side a face plate of celluloid 3, which is provided with a decorative device 4. The plate 3 iS Secured .to plate 2 either with or without an additional interm ediate plate of celluloid 5, which if used is of a different ycolor designed to' add to the artistic appearance of the device, for instance, the plates 2 and 3 being'whiteand the medial plate 5 beingfblack.

The device is preferably made oblong in shape, and the plate 1 isprovided withstii'- ening side flanges 6, each formed medially with an earA lug tosupport the cross bar 7. The ends of the buckle arerounded as shown at 8, and theperiphery of the deviceis beveled so that` as viewed in Fig. 1, the edges of all of the plates are in view.4 l s The metal plateis kprovided adjacent to each end with a pair of` upstanding lugs 9 and 10, respectively, theflugs Slaty oner end being inclined in their permanent, position, and the lugs 10 at the opposite end being formed at aright angle with the face ofthe plate. Theplate 2 kisprovided with corre- Y,

shown in Fig. 5, and the apertures 12 being wider and provided with an upright inner edge and inclined outer edge,as shown also in Fig. 5.

The apertures 11 and 12 maybe formed by first punching similar diagonal holes extending convergently downward toward the center of curvatureof the plate. The aperture 12 may then be enlarged and modied by subsequently punching out a part'of its inner wall by a vertical punching operation, lThe lugs on plate 1 may be struck up by apunchpress.

The method of assembling the several parts and securing them together is as follows: The plate'l is applied to plate 2 by inserting the lug 9 lengthwise into the aperture 11, as shown in Fig. 5, and simultaneously inserting lug 10 into the aperture 12. The lug 10 is then bent outward to a position corresponding substantially with that of lug 9. With the lugs thus disposed, they engage and interlock with the louter edges of their corresponding apertures, as shown in F ig. 7. Suitable liller material 13 is then ap pliedto the unoccupied parts of the apertures 11 and 12, so that the outer surface of plate 2 is smooth and unbroken. The material 13 is preferably in the form of cement formed by dissolving celluloid in a suitable solvent, preferably amylacetate. The next plate 5 of` celluloid is then applied to said. plate 2 andis secured thereto by means of acetone applied to the surfaces, and which serves to unite them integrally.

If a third plate of celluloid 3 is used as shown in Fig. 7, this plate is also secured in place by the use of acetone.

In order that the face of the topmost plate may present an attractive appearance, a dec-- orative design made of sheet Celluloid is then cemented thereto as shown in Fig. l, acetone being used as above prescribed. rlhe ornamental attachment may be variously designed, but a monogram or series of letters is considered preferable. lNhen the tep plate is white, the appearance of the design may be improved if suitable celoring le is applied to the plate surrounding the letters or other decorative device, in order to iinprove the background and provide a pleasing contrast. This coloring may be applied in the forni of pigment mixed with acetone, which causes the coloring material to penetrate indelibly, so that when the acetone evaporates, the coloring material appears `to be integral with the celluloid.

Although but one embodiment of this invention and a certain series of detailed steps are herein shown and described, it is to be understood that some of the details of the construction shown and also some of the steps in the process may be modified or omitted., without departing from the spirit of this invention as defined by the following claims.

l claim:

l. An article of manufacture, comprising a metal plate, a sheet of celluloid mounted thereon, fastening means extending from said plate through said sheet and interlocking therewith, and a second sheet of celluloid coveringsaid fastening means and integrally cemented to said first sheet.

2. An article of manufacture, comprising a support having a projecting lug, in combination with a celluloid plate covering said support and having a perforation in which said lug is secured, and second celluloid plate covering said perforation secured to the first-mentioned'plate in a substantially integral manner.

l 3. A belt buckle, comprising a support having a projecting lug, in combination with a celluloid plate having a perforation in which said lug is secured, means of cementlike character filling the space about said lug and substantially integral with- 'said plate to provide a smooth outer surface, and a second celluloid plate overlying the firstmentioned plate and cemented thereto in a substantially integral manner.

4. The method of applying celluloid ornamentation to a metal body, which consists in fastening a layer of celluloid to the metal by metallic fastening means extending through said layer, then mounting a second layer on the first to cover the fastenings, and causing the two layers to coalesce by means of a volatile solvent.

5; The method of applying a celluloid facing to a metal backing, which consists in providing a pair of celluloid plates of the desired size and form, securing one of said plates to said backing by means of corresponding lugs and apertures provided therefor, and then cementing the other plate to the first-mentioned plate.

6., The method of constructing an article of manufacture which consists in striking up lugs on a metal plate, punching holes in a celluloid plate, applying said plates face to face with said lugs in said holes, bending one or more of said lugs to positively engage the opposite plate, whereby the plates are fastened together, and cementing another celluloid plate to the first one.
